Related Parts Additional or alternate parts to consider.

The secondary door switch is a simple on/off mechanism that stops the microwave from operating when the door is open. The switch monitors the door latch position, and communicates whether the door is open or closed to the electrical control board. This door switch is approximately 1 inch long, and has 2 metal prongs called terminals that extend out of its body. Common symptoms related to a faulty secondary door switch include: microwave will not turn/shut off, or the microwave will not heat properly.
NOTE: Before you begin this repair, first make sure your microwave is unplugged, and that your capacitor is discharged. A capacitor stores large amounts of electricity even when your microwave is unplugged.

I saw a similar problem description at partselect.com and was confident to take the challenge to repair it myself. (Thanks to partselect.com). When I opened the microwave cover I found 3 similar switches. 2 of them works the same way and the other in reverse direction. Image diagram provided to buy parts is helpful to identify the switch.Steps:Remove the built-in microwave from the wall and keep it in an open space.Remove the microwave screws and take the cover out.Remove the 2 screws(inside) from the plastic panel where switches are snapped inGently remove the faulty switch and replace with the new one.(In my case the topmost secondary door switch was broken)

(be careful not to drop oven)Set the oven on kitchen counter. Took off five screws that held the vent cover. Removed vent cover. Took out one screw that held the control panel. Lifted, turned and slid the panel into the space below so I could get to the upper door switch. Replace door switch and re-assemble.

After closing door the display panel must be tapped on to keep the unit operating.

The switches are not the problem! The problem is in the tolerences of the latch housing. I have ordered two new housings (Upper & Lower) and will see if the tolerences are closer. If not I will try epoxying a shim to the plate that operates the microswitches. The other option is to file the mounting slots of the housing to allow adjustment, which would be iffy,keeping them from moving with use. The exploded drawings really need to be clarified. The scale is way too small. It was extremely difficult to pick out the individual parts of the mechanisiam.

Microwave will not start

Removed three screws from the top front cover and slide it out and following I removed the touch panel and the housing that holds the switches and replaced the bad one.
